Michael Garver moved into his new Sotherby home two months ago. Within the past two weeks, letters started arriving in the mail from subcontractors threatening to put liens on his house and demanding thousands of dollars.

"It's certainly frustrating to have people coming after you for things that you — in your mind — have already paid for," Garver said.

The Frisco father said he is now dealing with collection demands that shouldn't be aimed at him.

"They're demanding we pay the bill that Sotherby was supposed to pay — that we paid for in the house," he said.
